I say it dependence on your eyes, I can have flat depth with my both eyes open, what happens, your weak eyes would shift up and left to align the image on the dead spot ( or blind spot ) of your eye's retina (where all your optics nerves are bundled together). And, I can see both the rear sight, front sight and the target all focused, it is as if you put your camera focus at infinity in high f-stop.

Note, I am one of those 7% who did not develop stereoscopic vision while growing up.
